tachycardia
Let an agent explain tachycardia and its types in neutral clinical terms, relay causes, assessment and treatment in general from cardiology sources, describe warning signs, and route symptomatic people to clinicians and emergencies to emergency services.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain tachycardia and its types in neutral clinical terms, relay causes, assessment and treatment in general from cardiology sources, describe warning signs, and route symptomatic people to clinicians and emergencies to emergency services.
A heart rate faster than normal, generally above 100 beats per minute at rest in adults, arising as sinus tachycardia in response to exercise, fever, anxiety or illness, or as an arrhythmia such as supraventricular tachycardia including atrial and reciprocating forms, atrial fibrillation and flutter, ventricular tachycardia and, in its most dangerous form, ventricular fibrillation, which is a cardiac arrest rhythm; tachycardia is assessed by ECG and treated according to cause, from reassurance to medication, ablation and defibrillation.
What it is for: Not applicable; a clinical finding.
It can be explain types and causes; relay assessment and treatment; describe warning signs; route emergencies.
Distinguishing features
Fast rate
Physiological or arrhythmic
ECG classification
Range from benign to fatal
What it looks like
Not a visible object; a fast heart rate on ECG or pulse.
Physical character
adult threshold: 100 beats per minute - at rest
SVT typical rate: 150-250 beats per minute
ventricular fibrillation: no effective output note - cardiac arrest
How it is recognised
Heart rate above about 100 per minute at rest
Sinus, atrial, supraventricular, reciprocating and paroxysmal tachycardias, ventricular tachycardia, ventricular fibrillation
Bradycardia is a slow rate; palpitations are the sensation; normal exercise rates are physiological
